. Anywho... the gvwr of said half ton was 7700lbs? the following years went to smaller rear axles but kept the 7700lbs gvwr?SD's have a 6100lb RAWR for a 10k GVWR. Similar ratio.

OK... lol I guess I researched but not far enough. From what I read this 10.25 was only in a f150 year 2000. Now I'm told it was all the way through to 2008. And it even had disk brakes way back when. Cool
So in my one ton srw lays a 11.5aam rear axle rated for 6150lbs it sees less than 5000lbs at the heaviest ussually more like less than 3000. gvwr at 9900 puts the 6150lbs wr of the rear axle sounding pretty well overkill also untill u think of the 19000lbs its hauling up rocky mountainpasses with truck and fifth wheel combined all fulled up. Then it seems more like ensurance

You also need to realize that the 6100lb RAWR on the SRW superduties is because they are running you right at the max rating of the tire! The 11.5 axle itself is rated to 10k or more so you're at the mercy of the tires.
The regular F150 RAWR of 4050 is only a fraction of the 5000+lb total capacity of the P tires. The 4800lb HD payload rear axle is only a fraction of the 6000+ lb rating of the same E tires as 3/4 tons.
I'd rather rely on axles and bearings than a tire at max capacity. How many blown tires do you see on the side of the road vs the number of broken axles

However this method prevents more errors by the driver who doesn't understand all the ratings.

Michelins rated to 3195 times two equals 6390lbs beyond rated 6150 of rear axle. Not sure what original tires were rated at perhaps slightly less waaaay back in 2003 e ratings.
